Best ResponseYou've already chosen the best response.0x+y=170 xy=26 __________ So x=26+y 26+y+y=170 solve for y, plug and chug the first eqn to get x

Best ResponseYou've already chosen the best response.0You know that x and y together are 170 You know the difference is 26 So you know x or y being added to 26 is y or x respectively (doesnt matter) So you sub that into your first eqn. Then solve.
